 * Letters marked by * are not implemented but reserved by Unicode standard.
 *
 * Letters marked by ! are non-standard, but implemented by date-fns:
 * - `o` modifies the previous token to turn it into an ordinal (see `format` docs)
 * - `i` is ISO day of week. For `i` and `ii` is returns numeric ISO week days,
 *   i.e. 7 for Sunday, 1 for Monday, etc.
 * - `I` is ISO week of year, as opposed to `w` which is local week of year.
 * - `R` is ISO week-numbering year, as opposed to `Y` which is local week-numbering year.
 *   `R` is supposed to be used in conjunction with `I` and `i`
 *   for universal ISO week-numbering date, whereas
 *   `Y` is supposed to be used in conjunction with `w` and `e`
 *   for week-numbering date specific to the locale.
 * - `P` is long localized date format
 * - `p` is long localized time format
